Zhitai (致态) launches TiPlus9100 — its first PCIe 5.0 SSD built on Yangtze Memory (长江存储) Xtacking 4.0 flash

A domestic PCIe 5.0 flagship

Zhitai (致态) today unveiled the TiPlus9100, the TiPlus series' first PCIe 5.0 solid‑state drive and one of the first consumer SSDs to ship using Yangtze Memory Technologies' (长江存储) Xtacking 4.0 (晶栈) flash architecture. The launch underscores China’s push to move higher up the NAND value chain and to field home‑grown components that can power gaming laptops, thin-and-light notebooks and DIY desktops alike.

Reported performance and design

It has been reported that the TiPlus9100 achieves up to 12,000 MB/s sequential read and 10,700 MB/s sequential write, and supports roughly 1.85 million IOPS for random read/write workloads even without an independent cache design. Reportedly, firmware-level algorithms are used to trim power draw and improve thermal behavior under sustained heavy loads, and a single‑sided PCB layout is intended to broaden compatibility with compact notebooks as well as desktop builds. Zhitai also bundles its Tianshu Master (致态天枢大师) management software for benchmarking, system migration and real‑time health and temperature monitoring.

Why it matters — and the wider context

For Western readers: Xtacking is Yangtze Memory’s horizontally stacked approach that separates peripheral logic from NAND planes to boost I/O and manufacturing flexibility. The TiPlus9100 is part of a broader Chinese strategy to build a domestic memory ecosystem amid tighter Western export controls on advanced semiconductor tools and chips. Can Chinese NAND combined with domestic controller and firmware stacks close the gap with Samsung, SK hynix and Western Digital? That is the question investors and system builders will be watching.

Pricing and regional availability were referenced in the original report; IT之家 attached pricing details to its coverage. As Chinese suppliers push PCIe 5.0 consumer SSDs into the market, buyers will judge them on sustained performance, thermals and software maturity — not just headline sequential numbers.
